HYDROCARBON-BURNER.

' :specification or Letters Patent. 'latcut'cdMay 22, 191m Application inea neeember s, 1915. serial No. 65,654.1

To all whom t may concern:

Be it known that I, WILLIAM J. Bus'r, a

,citizen of the United States, and aresident of Detroit, in the county of Wayne and State-A following is a specification.

of lllichigan, have invented a newv andimproved Hydrocarbon-Burner, of which the This invention relatesto 'burners for alcohol and' the heavier liquid hydro-carbons such as'kerosene, and its object is'to provide a'burner wherein the parts will long retain.

' their shape and wherein maximum heat wil pis an elevation of the parts constituting the inner chimney and the trough. -Fig. 3 is a plan of the upper section of the inner Chim-j ney. Fig. 4 isa plan of thel lower section of the inner chimney. Fig. 5 is a section otv the lower 'ends 'of the -chimneys andthet'rough. n I v Similar reference characters refer to like parts throughout the several views.

In the accompanying Adrawing the inner. chimneyis shown to'be formed of three sections-1, 2 and 3, the upper section being.

Closed by means of a top 4.- The upper end of the-lower section is preferably drawn.

with an inwardly extending radialv flange .5 having an opening (l to permit airto pass` into the middle and upper sections. This flange 5 is formed lwith a ledge 7 adapted to receive the flange 8 of the interimaliate section. The ii1ter1nedi:ite'scetion isi'ormed vlwhich air'may pass into the space between `the sections, the hole 11 in the heads 9 and with a hea'dQ to which. the head 1 0. ot'the 'upper sectionmay be secured'in any desired I manner, and these two heads are formed with an opening 11 to permit airto pass into the upper section. Each of the three sections isl provided with a series-of holes `12-through 10 controllingv the amount of air whichmay pass into the upper section. .The amount of lair. passingv throughfthe holes 12' inthev lower andintermediate sections ispIeerably somewhat inv excess lof that necessary for the combustion of the hydrolcarbon fuel, and therefore the amountof airnecessary at.

the. openings l2 ot' the upperlsection may 'be relatively small.

`integrally torn'lcd on, welded or ybrazed to the lower end ot the lower sect1on1f1s a trough-14, best shown 1n Fig. 5, haring a Harige oir-shoulder 15v to center the asbestos wick 1G, and an inclined portion 1T that .Joins the part 1 ot the inner chimnev. rl`he trough is also Jformed with asecond'-circum- 'ferential` shoulder-1S that `is 'adapted to properlycenter the perforated outer chim.-

,iney 19. ledge 2() and cylindrical flanglje- ..21 con'iplctc the trough l l intol which the feed p1pe22 connects.

. Aeo\er 24 for the troughllas a flange thatI is preferablybrazedto the flange l21 on the ledge, an inclined portion 26,-an'd a" flange 27 that lits around the outer chimney. A Small-hood'o1-cowl QS is ,secured to the out'eifchimney and extends down'orer the upper. end ol' the llange Q7, being separated therefrom a ,sullicient listance to permit' a; vcurrent. ot' air vto .pass below its lower edge, -thence up between it and this flange?? and' then through the holes 2l) in the outer chimney, ez'irryingwith- .it any 'fuel 'vapors that may escal-)e between thisgllange'27 and the outerA ehinmey.

A shell or drum 31 .surrounds the outer chimney and has small brackets 32 secu red to itsin-ner 'aeethat rest on the cover of the trough. WhenI itis desired tolightwthe burner, a small amount of fuel -is permitted to flow. to the troughv through the` pipe 22,

of a wire which ball may be saturated with and l10 of the vseveral sections of'the inner chimney, these sections are substantially pre'- 'vented from warping out of shape, and .be--

cause of this, the proper. flame can be secu-'rd even afterthe burner has long-'been 1 in service. ledge-20 being integral Withv the inner chimney it will become quitel hot,

and the fuel from the pipe 22V Will be volatil-v ized and lioWarou-nd the outer chimney, en-

tering the space-l between' the chimneys vfamliafter satin-ating the Wick 1G, is. lighted b v`means of a small. ball oi" cotton on the end through the holes 34, then be lignited from the wick 16 and burn, air entering in proper amounts through the holes in the chimneys. The details and proportions of this burner may all be changed by those skilled in' theart without departing from the spirit of this invention.

I claim 1. In ahydro-carbon burner, the Combination of perforated outer and-inner chimneys and a trough integral with the inner chimney and supporting the outer chimney,

fmeans to feed fuel to the' trough, an' annular cover for said trough having a iangc at its inner 44edge extending up around the outer chimney, and a cowl secured to thev outer chimney and extending down over said flange but spaced therefrom, said outer chimney having holes between the flange and the cowl to'permit air to enter the space bey tween the chimneys. y

2. In'a hydro-carbon burner', the combination of perforatedouter and inner chimneys and a trough integral with the inner chim- ,ney and supporting the outer chimney,`

means to feed fuel tothe trough, an annular .cover forsaidtrough having a Hange at its inner edge extending up around the outer chimney, a cowl secured to the outer chimney and extending down'over said flange but spaced therefrom, said outer chimneyv having holes between the flange and the cowl to permit air to enter the space between the chimneys, and holes below the flange to permit fue] gas toenter said space from the trough.

3. In a hydro-carbon burner, an l inner chimney consisting of a plurality of sections, two of the sections having integral heads secured together and perforatedto permit to permit the passage of air, the lower section having an annular flange to support the other sections. .l

G. In a hydro-carbon burner, an inner chimney consisting of a plurality 'of sections and a partition wall in said inner chimney integral with one of said sections, the 'adjan cent section -being formed with an'inwardly extending flange resting on 'said partition.

In testimony whereof I sign this specification. i
